This flashy Blue Mud Dauber (Chalybion spp) was in my house taking
lazy short flights. I took it outside for some pictures:

Like the black and yellow Mud Daubers building a nest on Eleanor
Lindsay's house, the Blue Mud Daubers provision their nests with
spiders- Black and Brown Widows in their case. But instead of building
their own nests they use those of other Mud Daubers. The info I've
read in books and online is a bit vague but I believe they use
abandoned nests rather than taking over an active one. Someone might
be able to clarify this.
